Add form to html tabel cell - html

Question

I want to add an input form to an HTML table cell when a checkbox is selected.
When I add some form of text field or number field to the table cell to create a form, the text box doesn't show. only the text of my label shows.
<td>
<label class="collapsible">
<input type="checkbox" />
<span class="collapser">Edit</span>
<span class="arrow">></span>
<div class="collapsed">
<form method="post">
<label for="pwd">Hello World</label><br>
<input type="number" min="1" step="1" class="form-control" id="pwd" name=min_qty>
</form></div></label></td>
My Css code as well:
.collapsible {
display: block;
margin-bottom: 1rem;
}
.collapsible input {
position: absolute;
left: -9999px;
}
.collapsible input:focus ~ .collapser {
border-color: grey;
}
.collapsible .collapser {
cursor: pointer;
border: 1px transparent dotted;
}
.collapsible .arrow {
float: right;
margin-left: 0.5em;
display: inline-block;
transform: rotate(90deg);
transition: transform 0.25s ease-out;
}
.collapsible input:checked ~ .arrow,
.collapsible input:checked ~ .collapser .arrow {
transform: rotate(270deg);
}
.collapsible .collapsed {
font-size: 0;
margin: 0;
opacity: 0;
padding: 0;
/* fade out, then shrink */
transition: opacity 0.25s, margin 0.5s 0.25s, font-size 0.5s 0.25s, padding 0.5s 0.25s;
}
.collapsible input:checked ~ .collapsed {
font-size: 12px;
opacity: 1;
height: auto;
padding: 5px 0;
/* grow, then fade in */
transition: margin 0.25s, padding 0.25s, font-size 0.25s, opacity 0.5s 0.25s;
}

Answer 1

I figured it out.
My CSS was affecting all of my inputs, not just my check boxes.
Changed this:
}
.collapsible input {
position: absolute;
left: -9999px;
}
to this:
.collapsible input[type="checkbox"] {
position: absolute;
display: none;
}
